LT & HT Cabling

LT & HT Cabling

Course Description

LT and HT cabling includes all concepts about electric cable laying, clamping, cable glanding and termination. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Hence in this section, we include the factors to be considered in the cable selection.

This section helps you to enter into the next level of electric system supply, the HT supply. Here we are dealing with HT components like ACB, MCCB, Isolators, Panel Boards etc.

The earthing system plays a very important role in a network. Grounding your electrical system is a smart and easy way to make it a whole lot safer, as well as to protect against the very real possibility of having to deal with fluctuations in power supply. On the occurrence of an insulation fault or a phase being accidentally earthed, the values taken by the fault currents, touch voltages, and overvoltages are closely related to the type of neutral earthing connection. The extent of the damage to some equipment, such as motors and generators having an internal insulation fault, also depends on the earthing system. Hence earthing is a crucial factor to be considered by a system designer.
